Missed that - I am a little unclear how being wrapped in electron as an app is necessarily an advantage - I guess it could be valuable if it were pulled out electron, and you could host it as a service.
It's mostly just a nicely bundled way to run it if you aren't very technical but still want a easy to use database client.
You can also run commands like this to connect to your database if you want:
npx @outerbase/studio \ --port=5000 \ --user=admin --pass=123 \ mysql://root:123@localhost:3306/chinook
